Did you know it takes about 17,000 CPU instructions to print("Hello") in Python? And that it takes ~2 billion of them to import a module?

I doubt it's useful for performance evaluation, however, if you are writing a paper and want to compare your algorithm to an existing one, this can be handy

Eh, maybe? It's probably only useful for large jumps, and timing is also probably good enough for that as well. With small jumps, instruction execution order matters, so a bigger number could very well be faster if it improves pipelining.

It's certainly interesting and maybe useful sometimes, but it's probably limited to people working on Python itself, not regular users.
